Blindsight (Ex): Grimlocks can ascertain all foes within 40 feet as a sighted creature would. Beyond that range, they treat all targets as totally concealed (see Concealment, page 133 in the Player's Handbook).

Grimlocks are susceptible to sound- and scent-based attacks, however, and are affected normally by loud noises and sonic spells (such as ghost sound or silence) and overpowering odors (such as stinking cloud or incense-heavy air). Negating a grimlock's sense of smell or hearing reduces this ability to normal Blind-Fight (as the feat). If both are negated, the grimlock is effectively blinded.

Immunities: Grimlocks are immune to gaze attacks, visual effects, illusions, and other attack forms that rely on sight.

Skills: A grimlock's dull gray skin helps it hide in its native terrain, conferring a +10 racial bonus to Hide checks when in mountains. or underground.

Grimlocks are blind, but their exceptional senses of smell and hearing allow them to locate foes nearby. As a result, they usually shun ranged weapons and rush to the attack, brandishing their stone battleaxes.
